Garnet has many applications and is mainly used as an abrasive in abrasive blasting & water jet cutting and as a adsorbent in water filtration. It is also used in the preparation of non-skid tracks, steps, sports Ground Surface etc.

It is also used as abrasive media in Coated abrasives like Grinding Wheels and belts that are used in cleaning/polishing various surfaces like glass, ceramics, wood & metals.

SpeedBlast Blasting Grade Garnet is used for different jobs and to create different surface profiles.
It is used in offshore MGS, general marine structural steel, oil storage tanks, ships, rail cars, containers (mild steel and stainless steel), high chrome / nickel steel, pipes and sites that requires low dust limits.

Four major Blasting grades listed below are produced by SpeedBlast for Abrasive blasting for surface preparation.

Grade Profile Productivity Consumption
12/25 Mesh 110-130 microns 28m2 / hr 15kg /m2
20/40 Mesh 85-110 microns 28m2 / hr 12kg /m2
20/60 Mesh 70-110 microns 28m2 / hr 11kg /m2
30/60 Mesh 45-65 microns 28m2 / hr 9kg /m2

(Figures are based on blasting mild ‘B’ grade steel at 7 bars (required nozzle pressure) with properly set up equipment.It is recommended that accurate trial tests are conducted for each job).

Advantages of SpeedBlast Blasting Grade Garnet

  • The combination of tough mineral structure and rapid setting results in lower levels of dust creation during blasting.
  • Superior surface profile – garnet grains create a uniform profile virtually free of embedment, providing an excellent Surface for coating adhesion.
  • Cost-effective – highly effective, low consumption.
  • Non-toxic – inert and natural, crystalline silica levels are less than 1%.
  • Recyclable up to 5 times.
  • Easy cleanup.
  • Inert – will not interfere with your coatings.
  • Non-porous – will not draw moisture.

SpeedBlast supplies about 30,000 MTS of Blasting Grade Garnet per-annum; the quality of the product has been approved by several Oil companies in Far-East, Middle-East and Europe.

OGS produce Almandine variety Garnet of Indian origin, with its hard and tough sub angular grains provide the perfect balance between cutting speed and edge quality with reduced wear and tear to the equipment.

SpeedBlast Garnet with precise size and low dust is found to be effective in cutting stainless steel, marbles, granite, titanium alloys, glasses, garments etc. with high accuracy to any geometrical shape.

SpeedBlast has a separate processing facility exclusively to produce water jet cutting grades.
SpeedBlast Garnet gives trouble free performances without choking and clogging of the nozzles, since the product is of “Correct Grain Size Distribution, without any oversize material & Free of Dust.
